First, this is a user to user forum for troubleshooting and support. So, some information would be helpful for us to be able to help you.
How were you accessing playback? I’m still able to view the playback on all my v2, pan, and v3 cams.
If you’re referring to the events page: those have always been cloud recordings, they’ve never been SD recordings.
The Sd recordings can be found by clicking view playback on the live view of a camera, or by clicking the cloud recording on the events page and then clicking view playback.
Regarding the change to the events page, which are cloud recordings, Wyze sent out emails earlier this year regarding this upcoming change. In order to still view event videos rather than thumbnails on the events page you must subscribe to cam plus lite. There is a 0 dollar option, by clicking custom amount on the Wyze service page for cam plus lite.
